1. 5 th Biennial Ptolemy Miniconference Berkeley, CA, May 9, 2003 Models of Computation in Hollywood C. Fong

2. Ptolemy Miniconference 2 Background I was a student of Professor Lee from 1999-2001 I worked on the SDF, DT, GR domains of Ptolemy II I am now a special effects engineer in Hollywood This talk will be about how my education and use of MOCs in Ptolemy II has better prepared me for my current work

3. Ptolemy Miniconference 3 Models of Computation in Action SDF / DT for motion processing CT for dynamic animation GR scene graphs for geometric hierarchy

4. Ptolemy Miniconference 4 Motion and Animation

5. Ptolemy Miniconference 5 SDF motion signal processing

6. Ptolemy Miniconference 6 GR domain scene graphs presented in Ptolemy MiniConference 2001

7. Ptolemy Miniconference 7 Dancing Robot Scene Graph

8. Ptolemy Miniconference 8 CT-like dynamics

9. Ptolemy Miniconference 9 Geometry Dataflow Processing (Houdini)

10. Ptolemy Miniconference 10 Particle Systems Dataflow (Houdini)

11. Ptolemy Miniconference 11 Mixed MOCs example SDF (human motion) + GR (scene hierarchy) + SOPs (geometry) + POPs (water particles) + CT (dynamics)

12. Ptolemy Miniconference 12 Conclusion Models of Computation are useful in computer graphics and special effects Animation Packages like Alias/Wavefront Maya and Side Effects Houdini are components-based Future work …
